Thank you for these tips!
I assumed that using the run("Add to Manager") on an image without a selection would add the image boundary as a ROI, but I see now that it does not. It works as you describe.

Run the "Labels." command from the Image>Overlay menu and it will be recorded. Here is example that was created using the recorder:
run("Blobs (25K)");
makeOval(44, 27, 89, 98);
roiManager("Add");
makeOval(128, 119, 99, 98);
roiManager("Add");
run("Labels...", "color=red font=24 show draw");
roiManager("Show All with labels");

You can show the ROI Manager by pressing "t" (Edit>Selection>Add to Manager). This works when no images are open or the current image does not have an ROI. In a macro, use run("Add to Manager").
